We're pleased to report that they have little to worry about: While MGS4 surely represents a quantum leap in terms of accessibility and technology, it still retains the core elements that make the series so endearing. The Tokyo Game Show demo begins roughly 15 minutes into the game proper, dropping Snake (who's now jokingly referred to as "Old Snake" throughout) into the desolate, bombed-out city of Medina, Saudi Arabia on a mission to rendezvous with allies and search for Snake's nemesis, Liquid Ocelot. Visually, the game instantly impresses. The stark, harsh sunlight beats down on richly detailed streets as clouds of dust carrying bits of debris waft by. The world itself looks stunningly realistic, with a vast array of detailed textures covering the surfaces, a multitude of objects (including Snake himself) casting lifelike shadows (including perfect self-shadowing), and highly effective use of depth-of-field and subtle motion blur which lends the whole experience a graphical blitzkrieg unlike anything currently on consoles. Sure, MGS4 still falls back upon the series' long-running trick of reducing the color palette in order to up the visual fidelity, but it's such an evocative world that you won't complain. Likewise, the immersive 5.1 sound design does a remarkable job of transporting you to the battlefield, as distant explosions crackle in the periphery and haunting melodies weave in and out of the mix.
Before you set out on your mission, Snake receives a codec call from his old pal Otacon. The new Codec screen offers a full-color wide-angle view of your caller (but no image of Snake this time) that you can pan around, just as in MGS2. The big change here, however, is the ability to either fast-forward the message (that'll come in handy if Raiden's ladyfriend Rose calls to discuss her favorite monster movies) or rewind to catch key details you may have missed. Also, these codec scenes now feature full lip synching, and the U.S. version will also match up perfectly.
